“What makes you think I know anything about such things.” She extracted a bottle of green liquid from her pocket and took several mouthfuls.

I lifted one shoulder and let it fall. “It’s a long way from the Regent’s court to Pigalle.”

A muscle in her cheek twitched. “Far enough that perhaps I learned my lesson not to dabble in such things.” It was as much admission as I was going to get that she was familiar with the dark arts.

“I’m not interested in casting a curse,” I said. “I’m interested in breaking one.”

The muscle in her cheek twitched again, but otherwise, she looked unsurprised at my question. “You can’t,” she said, then sighed. “Although that isn’t precisely true. You can end a curse by ending the life of the witch whose will binds it.”

“There is no other way?”

She hesitated for a heartbeat. “No. None.”

Her reluctance made me feel uneasy. She was withholding information. “Why?”

Catherine took another mouthful from her bottle, refusing to look me in the eye. “A curse is an act of will, a desire, which is cemented by the magic of a sacrifice. It will continue until she no longer wills it, or until she dies.”

I straightened in my chair. “Does one need a name to curse someone?”

She huffed out a heavy breath. “I should think the witch would know the name of the individual she was cursing, but I suppose it isn’t necessary. Its only purpose is to create a focus.”

I considered her words for a moment. “So the witch who cast the curse is capable of breaking it?”

Another hesitation. “If she no longer willed it, then it would cease to be.”

I held my breath. There was something she wasn’t telling me. I could not say exactly how, but I felt in my gut that the other woman was holding information back. But why? What cause or care could she have whether I tried to break a curse that, for all she knew, had naught to do with her. Unless…

Her foot tapping resumed. The air in the shop was cool, but tiny beads of sweat were forming on her forehead.

“That’s unfortunate,” I said. “But perhaps there is something else you might help me with.”

“Oh?” Her eyes flicked to the door, then back to me.

“That spell you used to contact me through the fire, can you teach it to me?”

She settled into the chair. “That is a simple spell – all you really need is something of the person you wish to contact and fire on both ends. There are some plants you can put in the fire to fuel the magic, but a witch of even moderate ability has no real need of them.”

“What do you mean, something of them?”

Catherine shrugged. “A strand of hair. A fingernail. Blood.” Her eyes met mine. “It sometimes works if you have a possession belonging to the person. Something important. But not always.”
